Application filed Angust 10, 1916.

To all whom it may concern:

Be it known that I, RENE LINDEMANN, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Printing-Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a printing machine and has for its object the production of a simple and efficient machine for facilitating the printing of a sign or advertisement upon wrapping paper, bags and the like.

Another object of this invention is the production of a simple and efficient means for facilitating the handling of the machine, causing the device to be easily operated.

A still further object of this invention is the production of a simple and efficient means for feeding the ink or pigment to the printing roller.

With these and other objects in view, this invention consists of certain novel constructions, combinations and arrangements of parts as will be hereinafter more fully described and claimed.

In the drawings:

Figure 1 is a side elevation of the machine.

Fig. 2 is a top plan view thereof with the cover partly broken away.

Fig. 8 is a section taken on line 33 of Fig. 1.

Fig. 1 is a section taken on line 44 of Fig. 2.

Fig. 5 is a longitudinal section through a portion of the printing casing, the compression spring for the inking roller being shown in side elevation.

Fig. 6 is a detail sectional perspective of a portion of the side casing of the frame of the printing machine, showing the longitudinally extending slots formed therein.

Fig. 7 is a detail perspective of one end of the inking casing.

Fig. 8 is a front elevation of one portion of the ink receptacle.

Fig. 9 is a detail section taken on line 99 of Fig. 4:.

By referring to the drawings, it will be seen that 1 designates the outside casing which is provided with a hinged cover or top 2, the hinged cover or top 2 being Specification of Letters Patent.

Patented July 3, 1917.

Serial No. 114,250.

.hingedly secured to the rear plate 3 of the connected by means of a transversely extending handleS as illustrated clearly in Fig. 20f the drawings. A socket 9 is formed.

in the lower end of each of the arms 7 and one end of the spring 10 is seated in the socket 9 and held in firm engagement therewith by means of the set screws 11. The

spring 10 is provided with a coil 12 intermediate the ends thereof, and the free end of the spring 10 is provided with a hook- .portion 13 which hook-portion 13 engages a laterally extending pin 14f formed upon each side of the casing 1 as clearly illustrated in Figs. land 2 of the drawings. It

will, therefore, be seen that the casing 1 may be lifted from engagement with a sheet of paper or bag upon which the machine may be operated and that this spring will constitute a yieldable support for the body. It should be understood that the machine may be pressed downwardly upon a support for the purpose of facilitating the printing upon a sheet of paper or other material by the operator placing his hand upon the knob 15 or upon the top or cover 2 to regulate the amount of pressure desired.

A printing roller 16 is carried upon a shaft 17 within the casing 1 and this printing roller 16 is provided with suitable characters formed upon the outer face thereof as is indicated by the numeral 18 to cause the desired advertising matter or announce ment to be placed or printed upon the sheet of paper.

A plurality of inking rollers 19 are supported upon the casing l and have their bearing screws 20 working in the longitudinally extending slots 21 formed in the sides of the casing 1.

An inking receptacle 22 is carried by the casing 1 and this inking receptacle 22 is provided with a longitudinally extending slot 28 through which longitudinally extending slot 23 pass the wicks 2-1, one wick passing over the top of one of the inking rollers 19 and the other wick passing around the lower portion of one of the inking rollers 19. The ink is, of course, placed within the receptacle 22 and it will be fed out through the wicks 24 and be deposited upon the face of the inner or primary inking roller 19. As the primary inking roller engages the adjacent roller the ink will be forced from the first roller to the second roller and then from the second roller to the periphery of the printing roller 16. A cap 25 is fitted within the neck 26 of the inking casing 22 and is adapted to facilitate re-filling of the inking casing when so desired. 'Access may be had to the inking casing 22 by reason of the top or cover 2 which top or cover 2 is normally held in a closed position by means of a spring latch 27.

The inking casing 22 is provided with a journaled portion 28 at each end around which passes an eye 29 of the tension spring 80. The opposite end of the tension spring 30 is provided with an eye 31 which eye 31 engages each of the bearing portions 20 of the inking roller 19 so as to yieldably hold the two rollers 19 in firm engagement with each other and also for facilitating the holding of the rollers in firm engagement with the periphery of the printing roller 16.

From the foregoing description it will be seen that a very simple and efficient mechanism has been produced for thoroughly inking the printing roller and also for facilitating the moving of the printing casing over a sheet of paper or other material upon which it is desired to print an advertisement.

\Vhat is claimed is:

1. A printing machine of the class described comprising a casing, a cover there for, a printing mechanism carried thereby, an inwardly projecting yoke portion carried by said casing, a second yoke portion pivotally secured to said first mentioned yoke portion, an arm pivotally secured to said last mentioned yoke portion, a handle connected to said arms, and yieldable means connected to the lower ends of said arms and to the rear end of said casing to permit pressure to be regulated upon either end of said printing roller.

2. A printing machine of the class described comprising a casing, a cover therefor, a printing mechanism carried thereby, an inwardly projecting yoke portion carried by said casing, a second yoke portion pivotally secured to said first mentioned yoke portion, an arm pivotally secured to said last mentioned yoke portion, a handle connected to said arms, and a spring connected to the lower ends of said arms and detachably secured to the rear end of said casing for permitting pressure to be regulated upon either end of said roller.

In testimony whereof I hereunto aflix my signature. I RENE LINDEMANN.
